So it begins......When the mighty transcend to the heavens, and become gods!

Off Topic / Anyone use Retro Circuits before?
« on: April 17, 2018, 12:12 AM »
Anyone use this website before for repro carts?

EDIT: SA-1 is now supported

EDIT: I just realized that this might need to be moved to retro market place, so make of that what you will.

Mega EverDrive / GYM format??

EDIT: Lock or trash please. Whichever you prefer.

Mega EverDrive / SRAM
« on: July 16, 2014, 03:24 AM »
I know that the Mega Everdrive uses SDRAM for flash ROMs too, but is the chip for SRAM saves, SDRAM like for the ROMS or is it flash? I ask because theres a certain hack of Sonic The Hedgehog 2 that I want to try on my genesis and it writes to SRAM on every frame, which if played on Everdrive MD would use up writes. 

Off Topic / RKE insignia
« on: July 14, 2014, 07:20 AM »
On almost all the Everdrives (some don't have it) they have a circular logo on it that sometimes says "RKE" by it.

[ By the SMS pause button.

What is the significance of that logo and "RKE"? Is just a watermark to ensure that the cart is genuine?

Mega EverDrive / How get USB working on Mac?
« on: April 12, 2014, 01:31 AM »
So I understand that Mega Everdrive comes with a USB port to hotload ROMs into the 10MB SDRAM for homebrew and debugging purposes. Does anyone know how to get it working in Mac OS X? The necessary chip drivers are installed.

EverDrive GB / Gameshark support?
« on: April 06, 2014, 08:17 AM »
Will there be support for Gameshark codes (or at least in the future)? AFAIK nobody ever really used Game Genie for Gameboy, since it's easier to modify games using RAM values from gameshark like PAR codes.

EverDrive N8 / UNIF Format support.
« on: March 29, 2014, 10:19 PM »
I know I asked this once before, but I'm not going dig up an old thread. Will there ever be support for ROM files in UNIF format? Occasionally there will be some out there that will be in that format. There aren't any utilities on the internet that I could find that could convert from UNIF to iNES. It's quite a pain in the ass to have two different formats where everybody uses one and not the other.

Mega EverDrive / Transfering saves from EDMD folder to MEGA folder
« on: November 21, 2013, 08:23 AM »
I'm trying to transfer SRAM saves from the /EDMD/SAVE Folder to the /MEGA/SAVE folder. Is there any way to do this? I've used both Mac OS X and Windows to copy them and the files are completely hidden making it impossible to copy. Any way around this?

EverDrive N8 / Obscure NES/Famicom Mappers
« on: November 19, 2013, 02:45 AM »
This in response to another topic and these two posts from said topic:
I wish mapper 90 was supported by N8, it has really good pirates such as Tekken, Super Mario World, Mortal Kombat, Aladdin, etc. That would really be something, as PowerPak and anything else doesn't support this.
Disch once said about this mapper:
This mapper is such a big pain in the ass.  Not only is it overly complicated in every possible way, but
 every single game that uses it SUCKS.  Plus the composers for these horrible pirate games must have been
 tone-deaf, because the music is always out of key.  I freaking hate this mapper with a passion (can you
Didn't want to bump that thread, since last post was in February.

Lengthy post warning! :)

So, we all know that iNES format supports 255 mappers. Over half of them are used by chinese rom hacks, bootlegs, and chinese originals. Almost all of the mappers used by licensed games are supported which is a good 90 mappers or so. I know some people would think it would be silly to implement certain chinese mappers saying "lol thar just pirates play on an emulatr lolz", But some of them, despite the fact that a lot of pirate games suck, are pretty damn decent and very good and people like me (who have a very weird obsession with 8-bit NES pirate ROMS!) want to play them on the real hardware and not inaccurate emulators. Best example are games made by Hummer Team, known for making pirate games like the famous Somari and Kart Fighter. A lot of their more obscure games are on more complex mappers such as Mappers 90, 116, 121, 123, 187, 208, 209, 211. Disch, a hacker on NESdev who helped make documents for most of the iNES mappers, has said that some of these pirate mappers are hard and complex to reverse engineer. That isn't entirely true. While it maybe true that Mapper 90, for example maybe very hard and complex to implement, it isn't. If you look at his notes, you will find that it's VERY similar to MMC3 (Mapper 4). Mappers 209 and 211 are the SAME thing as 90, the only difference is the extended name table control setting and 1 jumper setting and mappers 116, 121, 123, 187, and 208 are also (I assume) similar to mapper 4 as well. They are NOWHERE near as complex as MMC5 (Mapper 5). Sure the sound isn't exactly the best on some of these games (mainly due to the sound driver used NOT the mappers themselves), but they're quite fun to play. Sure Disch said that the mapper is a pain in the ass, but that's what he said back in 2006 when only half of the 255 iNES mappers were ever supported in mappers which, to be honest was just his opinion. Almost all NES emulators today have support for these mappers from the start. I hope that this post will encourage Krikzz keep up the good work that he's done for us, and go above and beyond what was thought possible with flash carts. Others can help Krikzz with programming of these mappers since the USB option on Everdrive N8 allows for this. Nestopia and FCEUX source codes are great sources to use for mapper programming!
FWIW I think that even the most obscure mappers should be implemented anyways to enlarge the NES/Famicom game library beyond what was officially released!

TL;DR Implement more obscure mappers for more NES/Famicom/Everdrive N8 awesomeness!!!

EverDrive MD / Soft megakey loads instead of hardware megakey
« on: September 25, 2013, 10:36 AM »
I just got a Model 1 HDG Sega Genesis. I know that sometimes megakey loads in software occasionally on my Model 2 VA2 Genesis. It's loading ALL the time on the Model 1 for whatever reason and games that rely on regional lockout don't work on the model 1 like they did on the model 2 because of it. Is there any way to get around that besides downloading [f] labeled roms? Cart works fine otherwise.

EverDrive N8 / File Formats question
« on: August 14, 2013, 12:07 PM »
So I ordered an Everdrive N8 off Retrogate for a Famicom I had ordered off Ebay, and was wondering what file formats does it take? Considering most NES/Famicom dumps are in iNES and very few are in UNIF, some NES ROMs I have are in UNIF format and was wondering if it'll accept both. Will the BIOS/Firmware not care what format it's in or not? :P

EDIT: Nevermind. I found out once I got the cartridge. UNIF roms need to be converted somehow to iNES format.

EverDrive MD / Weird blue "M" icon
« on: April 01, 2013, 11:04 PM »
Hi. New to the forums blah blah.....

There's a weird blue "M" icon that started showing up next to where it says 2X in the lower right hand corner of the screen on the Everdrive MD main menu on my cartridge. What does that mean? Sometimes it stays there when I turn off the system and turn it back on or sometimes it goes away. Cart works perfectly fine otherwise.
